AMANPOUR: Welcome to our viewers here and around the world. And there's lots to discuss today on the world stage and the campaign trail.
But first, we want to catch you up on some news since the Sunday morning papers, a major development today in the Republican race for the White House. In a midnight e-mail to his supporters, Indiana Governor Mitch Daniels has announced that he will not run for president in 2012. Daniels had quickly become the most buzzed-about non-candidate in the race, but his wife, Cheri, had veto power. And the governor acknowledged it in his statement today, saying, quote, "Simply put, I find myself caught between two duties. I love my country; I love my family more." And there's much more on this story coming up.
And huge plumes of smoke over Iceland this morning. The country's most active volcano is erupting and spewing clouds of ash into the sky. You'll remember a year ago another volcano in that country forced Europe to seal its airspace, stranding 10 million travelers, and now Iceland's largest international airport is closed.
And President Obama is preparing to address AIPAC this morning, the country's largest pro-Israel group, just a few hours from now, this after stirring up a hornet's net on Thursday when he outlined his vision for Middle East peace.
AMANPOUR (voice-over): The speech was billed as President Obama's response to the winds of change blowing through the Middle East. Instead, it set off a firestorm of criticism, both in Israel and from Republicans.
Governor Mitt Romney said, "President Obama has thrown Israel under the bus." Majority Leader Eric Cantor said the speech "undermines our special relationship with Israel." And Mike Huckabee, "President Obama has betrayed Israel." And Newt Gingrich caused it "disastrous."
The cause of all this uproar? Obama became the first U.S. president to so publicly endure something that's been the basis of negotiations for the last decade, also a key goal of the Palestinians.
OBAMA: We believe the borders of Israel and Palestinian should be based on the 1967 lines with mutually agreed swaps so that secure and recognized borders are established for both states.
